Why won’t my truck start?
I have a 2002 Ford Ranger automatic. I have
all power (headlights, radio, control panel,
etc.) My starter is good my ignition switch is
good all my fuses are good. But when i turn
my key i get nothing. It won’t crank over or
anything. Why?
Make sure battery has a full charge and connections all good. I did look up your security system, it said starter motor disable among other components. Any applicable trouble codes, relating to security system? It might be possible with testing to see if starter motor will crank the engine. If you try that, make sure transmission is in park or neutral and parking brake is set. Make sure vehicle can't move. The diagram is for starter circuit.
Thank you. Yes battery is fully charged and yes truck will start with the starter. But no codes have came up at all.
If you jump the starter motor, are you saying the vehicle will start and run? See terminal 30 at starter relay, fuse protected and hot all the time, use a test lite, check for voltage. Terminal 85 at the relay, should go hot with key in the crank position and should be wired through transmission range sensor, check that terminal for voltage. You can unplug the relay and use test light on those terminals.
